What is the difference between clay bricks and three-level high alumina bricks?

Farqiga ugu weyn ee u dhexeeya lebenkii dhoobada ahaa iyo lebenkii alumina-sare waa ka kooban aluminium iyo cufnaanta badan.

Lebenkii 40-48% ka koobnaa aluminium waa lebenkii dhoobada ahaa. Lebenkii dhoobadu waxay leeyihiin tilmaamayaal kala duwan oo ah N-1, N-2, N-3, iyo N-4 ee heerka qaranka. Wax-soo-saarka iyo adeegsiga, N-2, N- 3 lebenkii dhoobada ayaa si weyn loo adeegsadaa, sidoo kale waa badeecooyin caadi ah oo ay soo saaraan soo-saareyaal badan. Cufnaanta mugga ayaa u dhexeysa 2.1-2.15. Marka laga hadlayo lebenkii dhoobada N-1, tilmaamayaasha qaarkood waxay ka sarreeyaan lebenkii alumina ee fasalka saddexaad ee sare.

Bricks with 55% aluminum content are third-grade high-alumina bricks with a bulk density between 2.15-2.25. At present, due to the production area and raw materials, the aluminum content of clay bricks is about 56%. The aluminum content of the clay bricks in Xinmi, Henan is about 56%, and the body density is above 2.15, which is basically a third-grade high-alumina brick. Moreover, the firing temperature is high, and the chemical index is not lower than the third-grade high alumina brick, but there is a difference in the softening temperature of the load.

The aluminum content of the three-level high alumina bricks currently produced is about 63%, and some have 65%. The body density is above 2.25, and the load softening temperature is slightly lower. In terms of chemical indicators, it is only different from the second grade high alumina bricks in unit weight and load softening temperature.

Midabka muuqaalka ee lebenkii dhoobada ahaa iyo lebenkii fasalka saddexaad ee alumina sare weli wuu ka duwan yahay. Lebenkii dhoobadu waa casaan-huruud, iyo lebenkii fasalka saddexaad ee alumina sare waa caddaan iyo huruud.

Waxaa jira farqi xagga miisaanka ah oo u dhexeeya lebenkii dhoobada ahaa iyo saddexdii leben ee alumina sare ahaa. Lebenkii dhoobada ahaa ee la midka ahaa ayaa ka khafiifsan fasalka saddex leben ee alumina sare. Heerkulka dabka ayaa sidoo kale ka hooseeya 20-30 ° C.

Lebenkii dhoobada ahaa iyo saddexdii lebenkii alumina ee sare ahaa waxay ku kala duwan yihiin xoogga cadaadiska iyo kulaylka jilicsanaanta culayska. Awoodda cadaadiska ah ee lebenkii dhoobada ahaa 40Mpa, halka xoogga cadaadiska ee fasalka saddex leben ee alumina sare yahay 50Mpa. Culayska jilicsan ee lebenkii dhoobada ahaa ayaa waliba ka sarreeya kii darajada saddexaad. Dib-u-dhiska birta aluminiumku waa 30-40 ℃, iyo dib-u-habeyntiisu waxay ku dhowdahay 30 ℃.
